I have noticed something that I find interesting. Now, I have a mac on which I have VmWare so that I can run windows as well. This way I get the best from both worlds.
I have found that some files won't open in Windows but they do open on the Mac. it seem this only happens when I have downloaded hardcore pictures. I noticed the same problem when I download the same files from Windows. There's a mac freeware program called jpeg-jfif repair which does fix the problem. As far as I can see, these files have been damaged intentionally.
I sometimes wonder whether they have been damaged in such a way that it may exploit some weakness and serve as a platform for malware. Most likely, the payload would be stored as metadata. Thats one of the reasons I always have it removed.
Secondly, here's an interesting observation that I made. If uýpu open a jpg file using the default picture viewer in Windows and than use "Save As", the file will no longer be the same. Most of the time it will be significantly larger. For some weird reason, this program will re-sample the image and then save the file.
This will obviously defeat any program that finds duplicate files. It will be a near match but then you start wondering about which file is the better. It's very tempting to believe that a larger file is better than a small one and that one should use the first one ia file seems good enough to be enlarged
